To all, whom t may concern:

Be it known that I, EDWARD J. STEWART, a citizen of thepUnited States of America, and

a resident of Brookline, in the county of Nor` struction and arrangement of parts, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Of the drawings, Figure 1 represents a plan view of a shipping-case embodying the feaf tures-oil this invention. Fig. 2 represents a longitudinal sectional elevation of the same.

Fig. 3 represents aninside elevation of one of the retaining members. Fig. 4 'represents a plan of the same; and Figs. 5` and 6 represent enlarged sectional details of the cover-retaining members, showing a portion of the cover ooacting therewith.

Similar characters designate like parts throughout the several figures of the drawings.

In the drawings, 10 represents a case of ordinary construction, having secured at its op.-

posite ends coverfretaining members 11 12. These retaining members 11 and 12 are shown as extending from one sidewall 13 of said case to its opposite side wall; but it is obvious that the members 11 and 12 may extend for a less distance or be divided into several sections separated from each other and .accom plish the object of this invention `reasonably as well, although the `preferred form is, as shown in the drawings, with the retaining members 11 12 reaching from one side wall to the other. These retaining' members 11 12 are secured to the inner end wall of the case by any suitable securing means, as shown at 14, it being advisable to fasten these from the Acover into the grooves formed by said inwardly-extending anges 16 and 18. The retaining member 12 is provided with a spring l1.9, which is adapted to coact with the end of the cover 17 to force the samev tothe bottom of the groove formed by the inwardly-extending flanges 16 18 upon the retaining member 11, in which position the flanges 16 of said retaining members 11 12 will prevent the removal Vor accidental displacementof said cover 17 The spring 19 tends to retain the cover in this position indenitel y until said spring has been compressed, permitting Ythe movement of said kcover 17 to the rightof Fig. 2, 4so that the edge 20.011 said cover 17 will pass the edge ofl the Y flange 16 on the retaining member 11 and permit said edge20 to be lifted into the position shown in dotted lines in Fig. 2, when a movement of said cover 17 to the left of Fig. 2 will remove the same from engagement with the iiange 16 of the` retaining member 12. 4Awire 21 is passed through a hole 22 in the cover 17 Y andthrough ahole ,23. inthe end wall of the packing-case 10, and the ends ofsaid wire are .secured together by0 a seal24 to. hold the cover yin thebottom of the groove in the retaining .member 11 until thecase has reachedits destination, when in Vorder to secure .access tothe contents `1t will. be necessary tov breaky saidseal and disconnect the wire 21 toperrnit the rev moval of the kcover 17. The iiangelofl the.

retaining members 1112 projectsat 25. be-

, yond the edge ofthe iiange 16 to assistin the insertion and removal ofthe cover 17 by forming a support therefor during this operation. By this means a shipping-case is provided in which goods may be transported from one section to another securely locked and sealed, and upon reaching its destination access to the contents of said case may be readily secured by simply breaking the seal, which permits the removal of the cover 17 without the necessity of removing screws, nails, or other fastening devices, the implements for such removal not always being at' hand.

A great advantage of this device is that the cover is not injured by the use of fastening devices and will be returned to the sender in good condition ready to be forwarded again to another destination as soon as the case has been refilled. Another advantage is that the cover may be readily removed without the use of tools.

It is obvious that by the use of this invention a great saving to the manufacturer is made both in materials and time. The cases are closed without the expense of nails, screws,

stood.

Having thus described my invention. I claim- 1. The combination of a box, inwardly-projecting plates secured to two of theinner walls thereof, a cover adapted to it between the other walls of said box and beneath said plates, means for supporting said cover when in closed position, and a spring adapted to coact with the edge of said cover to retain it in closed position.

2. The combination of a box having four vertical sides of equal height, 'inwardly-projecting plates secured to the interior wall of two opposite sides thereof, a cover of a width equal to the width of the interior of the box and of a length equal to the interior length of said box minus the depth of projection of one plate, and an inwardly-projecting lip beneath each plate to form a support for said cover.

3. The combination of a box, plates secured to two opposite inner Walls of said box and projecting inwardly therefrom, a cover adapted to fit between the other walls of said box and beneath said plates, an inwardly-projecting lip beneath said plates to form a support for said cover, and a spring adapted to coact with the edge of said cover to retain it in closed position.

4. The combination of a box, two grooved plates secured to opposite walls thereof, a cover adapted to enter said grooves, and a spring adapted to force said cover to the bottom of the other groove.

5. The combination of a box having four vertical sides of equal height, inwardly-projecting plates secured to the interior wall of two opposite sides thereof, a cover of awidth equal to the width of the interior of the box and of a length equal to the interior length of said box minus the depth of projection of one plate, means for supporting said cover when in position beneath said plates, and locking means to prevent the removal of said cover.A

6. The combination of a box, two inwardlyprojecting plates secured to opposite walls thereof, a cover adapted to t between the other walls thereof, means for supporting said cover when in closed position, a spring beneath a plate at one end of said' box, and a device at the opposite end of said box for locking said cover in closed position.

7 The combination of a box, two grooved plates secured to opposite walls thereof, a cover adapted to enter said grooves, and means located in one groovedy plate for forcing the cover to the bottom of the other grooved plate.

8. The combination of a box having four vertical sides of equal height, inwardly-projecting plates secured to the interior wall of two opposite sides thereof one plate extending 'inwardly from the interior wall a greater distance than the other, a cover of a width equal to the width of the'interior of the box and of a length equal to the interior length of said box minus the depth of projection of the lesser plate, and means for supporting said cover when in position beneath said plates.

9. The combination of a box having four vertical sides of equal height, inwardly-projecting plates secured to the interior wall of two opposite sides thereof one plate extending inwardly from the interior wall a greater distance than the other, acover of a width equal to the width of the interior of the box and of a length equal to the interior length of said box minus the depth of projection of the lesser plate, means for supporting said cover when in position beneath said plates, and means secured to the end having the lesser plate for locking the edge of the cover against the interior wall of that end of the box.

Signed by me at Boston, Massachusetts, this 2d day of February, 1904.
